Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 As shown, a novel high-speed light gas gun muzzle ejection damping system of the present invention comprises an ejector cavity 1 that is threadedly connected with the high-speed light air gun barrel, and is sequentially connected with the ejector through a plurality of positioning shafts 4 The viscoelastic high damping rubber pad 2 and the flipper baffle 3 connected to the device cavity 1, each positioning shaft 4 is covered with a coil spring group 5, and the coil spring group 5 on each positioning shaft 4 is sleeved on the positioning shaft 4 The coil spring partition 6 on the top is divided into two parts, and the end of the positioning shaft 4 away from the ejector chamber 1 is threadedly connected with a double-tube ejector shock absorber 7 .

[0020] Such as figure 2 As shown, the inner diameter of the...

Abstract

The invention discloses a novel high-speed light-gas gun muzzle bullet-separating vibration damping system. The system comprises a bullet-separating device cavity connected with a high-speed light-gas gun barrel via threads, and a viscoelastic high-damping rubber gasket and an elastic supporting baffle connected with the bullet-separating device cavity in sequence via a plurality of positioning shafts, each positioning shaft is sleeved by a spiral spring group, the spiral spring group of each positioning shaft is segmented into two parts via a spiral spring separating plate sleeving the positioning shafts, and end parts of the positioning shafts, far away from the bullet-separating device cavity, are connected with double-cylinder bullet-separating vibration dampers via threads. The high-speed light-gas gun muzzle bullet-separating vibration damping system is advantageous in that the occupied space is small, the mass is small, the system is detachable and portable, a bullet holder can be recycled, and the buffer effect is good; the bullet-separating vibration damping system and the barrel and the double-cylinder bullet-separating vibration dampers and the positioning shafts are both connected via the threads so that the dismounting is facilitated; the impact effect on a bullet-separating device by the bullet holder is alleviated via vibration damping spiral springs; and rapid attenuation of the vibration of the bullet holder is realized via the viscoelastic high-damping rubber gasket and the double-cylinder vibration dampers.

Description

technical field [0001] The invention relates to the technical field of light gas gun systems, in particular to a novel high-speed light gas gun muzzle ejection damping system. Background technique [0002] The light gas cannon system can make the projectile produce a speed as high as 50-8000m / s. The light gas cannon is a kind of experimental result with good repeatability, good parallelism and flatness in the impact process, and has the advantages of simple operation and convenient detection. system. Widely used in dynamic loading experiments. The light gas cannon system consists of a breech high pressure chamber, barrel and recovery chamber. During the experiment, after placing the experimental specimen in the recovery chamber in front of the barrel, the breech high-pressure chamber is filled with high-pressure gas, and the projectile fixed on the bullet holder is placed in the barrel, and the high-pressure gas is released to drive the bullet holder and the projectile tog...
